A shock rebuild or shock service includes disassembling, inspecting, and rebuilding a shock absorber to restore its performance and prolong its lifespan. This can include replacing worn or damaged internal components, such as seals, shock oil, and new nitrogen. This process should be performed by a qualified mechanic or suspension specialist and is typically recommended at regular intervals based on usage and wear. In general, experts recommend shocks be rebuilt at least every 2500 miles – more frequently if you race or ride fast in rough terrain. Just like your engine or transmission, shocks need to be serviced regularly to perform at their best.
Over time, shocks can degrade in a few ways:
- Shock spring break-in, general sag from lower quality OEM springs, and/or sag from additional weight (spare tire, cooler, tools, fuel, etc.)
- Loss of nitrogen pressure and/or oil
- Worn-out shock oil
- Wear and/or damage to internal components (seals, etc).
If you own a Polaris RZR XP1000 that is more than a couple of years old, your shocks are probably in desperate need of a little TLC. First is the shock rebuild. Second, your springs have settled and are sagging due to additional weight added to the vehicle or they may be just tired. End result is decreased ground clearance and shocks that may blow through the travel faster than they used to. Both of which are signs of sagging springs and shocks in need of service.
The two biggest improvements you can make to your suspension on a RZR XP1000 that is a few years old are a Shock Rebuild and a Dual-Rate Spring Kit!
If you are local to Phoenix, AZ, you can bring your RZR or just your shocks to Shock Therapy. Otherwise, you can ship your shocks to them for rebuild and upgrades (How to Ship your Shocks for Service and Upgrades).
